General information
The piping installation must be executed according to
the applicable standards and directives.
HK 200M indoor unit, with NIBE Monoblock outdoor
air heat pump, and NIBE SMO controller form a com-
plete heating system.
The system can cooperate with a low- and medi-
um-temperature heating system. Recommended
temperature of the heating medium at minimum de-
signed outdoor temperature DOT must not exceed
55°C on supply, and 45°C on return circuit from the
heating system, whereas HK 200M can achieve even
65°C when using a ow-through heating module or
another peak heat source.
Excess medium owing out of the safety valve must
be discharged via a pipe to a oor drain. The over-
ow pipe must be slanted at the entire length from the
safety valve, and must be secured against freezing.
In order to achieve maximum system efciency, we
recommend the installation of HK 200M as close to
the heat pump as possible.
The HK 200M module is not equipped with cut-off
valves, which must be installed outside the indoor
module to make future maintenance easier. The HK
200M module can be connected to the central heat-
ing, cooling, and domestic hot water installation. In-
stall the supplied safety valve and the manometer.
HK 200M is equipped with a diaphragm expansion
vessel for a heating circuit of 10 I. Initial pressure of
the expansion vessel must be set appropriately to
the maximum height (H) between the vessel and the
highest heater, see the drawing. The initial pressure
of 0.5 bar (5 mvp) shall mean maximum permissible
height difference of 5 m.
If the standard initial pressure in the diaphragm ex-
pansion vessel is too low, it can be raised by lling the
vessel through the valve installed.
Any change to the initial pressure affects the dia-
phragm expansion vessel’s capacity to support the
increase in water volume.
IMPORTANT
All places in the heating system located high must be
equipped with vents.
IMPORTANT
Pipelines must be rinsed before connecting the indoor
module so that possible dirt does not damage its ele-
ments.
IMPORTANT
As long as heating circuits in the system have not been
led with the heating medium, do not set the switch
(SF1) in the SMO module in position “I” or “ ”. The
compressor in the heat pump and the ow-through
heating module can be damaged.
Capacities of the indoor unit and the
heating system
System requirements
The inner capacity of HK 200M for the purposes of
calculating the diaphragm expansion vessel in the
domestic hot water installation totals 180 l. The ca-
pacity of the diaphragm expansion vessel must con-
stitute at least 5% total capacity.
Minimum required conguration:
In order to assure correct operation, the capacity of
the heating system must meet the requirements for
the installation. If this condition has not been met, in-
stall an additional buffer tank. (NIBE UKV).
CAUTION
In this case a diaphragm expansion vessel of the
DHW installation must have the capacity of 10l. The
diaphragm expansion vessel at the domestic hot water
installation is not required. It is, however, required to
install a safety valve with opening pressure of 6 bar.
IMPORTANT
All connections require free ow, hence a discharge
valve must be installed.

The HK 200M indoor unit is equipped with a coil water
heater, diaphragm expansion vessel , safety group,
electric heater, isolation valves, plate heat exchang-
er, metering instruments, and an electronic circulation
pump. Together with the heat pump NIBE Monoblok
and NIBE SMO module, it forms a complete heating
system.
The F2030, F2040 8 kW; F2040 12 kW, F2120 8
kW; F2120 12 kW, F2120 16 kW outdoor unit pro-
vides heat for heating the domestic hot water and
supplying the heating system while using free ener-
gy in the outdoor air, efciently operating within the
range of low temperatures up to -20°C.
The connection of the outdoor unit and indoor unit
HK 200M with a system of pipes lled with a cooling
medium secures the connection against freezing in
the event of any power outages. The control of sys-
tem operation is the function of SMO 20 or SMO 40
module.
